Zhao Ta reported the victory to the Beijing Division, while sending scouts to find the whereabouts of the Jin army, and at the same time sent troops to attack Wenshui, Yuci, Taigu and other prefectures and counties occupied by the Jin army.

And at this moment, Zong Han also has news, this kid is suspicious, deceived the Song army defending the city, and then quietly led the army to flee first plundered Yuci, and then conquered Shouyang and plundered away, bypassing Taiyuan City into Xinzhou, garrisoning Chitang Pass and Shiling Pass.

"This kid is really ruthless!" After listening to the report, Zhao Ta said hatefully, Chitang Pass and Shiling Pass are the gateways to the north of Taiyuan, easy to defend and difficult to attack, as long as they occupy these two places, it is equivalent to mastering the key to the gate of Taiyuan Mansion, and they can go south at any time, and only by seizing these two passes, Taiyuan can be regarded as completely unencircled. So after a five-day truce, on the tenth day of July, Zhao Ta left 20,000 soldiers and horses to guard Taiyuan City, and he led 100,000 soldiers and horses north to prepare to seize the two passes, recover Xinzhou and Daizhou, and completely expel the Jin army from Hedong...

Besides, Zong Han withdrew from Taiyuan City, gave up the achievements of half a year, and the duck flew away again, which made him angry and helpless. Although there was only one battle between Sanjiaokou, this battle caused Zong Han to suffer nearly 10,000 casualties, which was enough to break his muscles and bones, although he couldn't determine whether he was meeting a group of people in Yingzhou, but he had already determined that there must be a connection between them, and he counted no less than 20,000 people who died in their hands.

The huge losses made Zong Han realize that he was by no means the opponent of the Hezhong Army in the field state, and even Sanjiaokou, the stronghold that controlled the valley pass, was far less dangerous than Chitang Pass and Shiling Pass. Not to mention that compared with Yanmen Pass, a military brigade stationed at Sanjiao can block the convoy that relies on official roads. But he couldn't stop the Hezhong army who was determined to save Taiyuan.

And if you fight a decisive battle under Taiyuan City, although you will line up with your back to the city. The side is worry-free, but can only be on the defensive, and also loses the mobility, if the three crossings are lost again, their access to the north will be intercepted, and they can't go if they want to, even if they don't fight themselves, they have to end up with the people in the city.

If he abandoned Taiyuan and continued field battles with the Song army on the outskirts of Taiyuan, he captured several prefectures and counties in Hedong. However, it is still inevitable that the depth is too shallow, and it is difficult to give full play to the advantages of roundabout movement operations, and the Song army can still adopt the tactics of step-by-step, and the result is that it is squeezed into a corner and it is difficult to escape the end of annihilation.

Just as Zong Han was thinking about it and weighing the pros and cons, news arrived that the Song Army's Hebei reinforcements had arrived in Jingcheng and were ready to re-take the road of the division - the soldiers went out of Shouyang. In that way, the route back to the north was completely blocked, and if you wanted to go back, you could only break through the encirclement and interception of the 300,000 army. Zong Han was arrogant, but he was not so mad that he couldn't do anything about himself, and immediately decided to withdraw from Taiyuan overnight. Retreat to Shiling Pass to hold the danger, and then deal with the Song army, once things are not good. But he also immediately withdrew from the Great Song Dynasty, so that he always held the initiative.

Although quitting Taiyuan is Zong Han's own choice. But what a nest in my heart! He tried his best to move the emperor to the south to attack the Song Dynasty, but Han Li couldn't come out on top. The soldiers were in Bianjing, but I heard that he met Shui Kou and returned to his family with 10 million taels of silver, which sounded outrageous, but Zong Han was still happy and laughed at him for being busy for a long time. I didn't expect the Tianli cycle, today it was my turn, and I fell short at the end of the day!

"Ceres, are we going to retreat here like this?" Wanyan Lou Room picked up the bowl and took a big sip of wine and said.

"Although I am unwilling, but at this moment it is the best policy, we have controlled Shiling Pass, we can go south at any time, and the Song army will not stay here for a long time!" Wanyan Xiyin replied with a smile.

"Well, the words of the god of grains are reasonable, and Song Jun won't last long!" Zong Han nodded and said.

"Marshal, we control Shiling Pass, the Song people will not be unaware of the importance of this pass, even if they are unable to recapture it, they will inevitably leave heavy troops to defend, how can they easily withdraw their troops!" Wan Yan Lou asked suspiciously.

"Hmph, we have paid such a big price, how can we go back empty-handed, if they don't leave, they can only be buried with Taiyuan City!" Zong Han snorted coldly and said.

"This..."The two of them said in a foggy manner, and after Yan Lou's room, the two of them still didn't fully understand what they meant.

"Lou Mur, the Song army is not as good as us in combat, we only need to carry a small amount of grain and grass to go on the expedition, and on the way, the military needs can be requisitioned on the spot to fight continuously, but the Song army can't do this!" Wanyan Xiyin explained.

"Oh, I understand, we just need to cut off the Song army's food channel, and they will be defeated!" Wan Yan Lou said suddenly.

"Yes, they have sharp firearms, but they can't afford not to eat or drink!" Zong Han nodded and said, suddenly feeling a little better in his heart...

………

In ancient times, the army was mainly fed with grain and grass. The Han army has to prepare military rations and transport them specially when they go out to fight, which has a great deal to do with the eating habits of the nation, and the Han soldiers must eat steamed buns, vegetables and meat, and drink porridge, and they cannot always make do, otherwise their morale and combat effectiveness will be affected. Therefore, whenever there is a war, it is necessary to collect and reserve a large amount of military rations, heavy grain and grass, sometimes for several years, and a large number of people must be called in to accompany the transportation, resulting in a shortage of labor and the abandonment of fields.

Once the war begins, if the battlefield is too far away and the transportation lines are long, the transportation will be more difficult, and the huge logistics will be vulnerable to attack. This led to the prohibitively high cost of the war, and therefore also made the conservative officials, as well as the majority of the population, oppose the war, which in fact also has a mass base.

The logistics of the nomadic army are very simple, first of all, they eat simply, and the soldiers who participate in the war carry their own food, and the dried meat can last for ten days and eight days. There is also an important one, that is, when the nomadic army is fighting, it is good at plundering the Han people to maintain consumption, relying on robbing the opponent's military rations, and digging up the grain cellars of the Han people to solve the logistics supply of long-distance attacks, and there is no need to consider the problem of providing logistics grain and grass for the brigade at all. The armies of the nomads feed the war with war, so the cost of war is very low.

This is not the most troublesome, the greater trouble is that the nomads have flexible and excited cavalry units, which can move quickly, which is conducive to finding weak links and attacking the baggage teams of the Central Plains army. The Central Plains army was on an expedition and had a long transportation line, making it particularly vulnerable to attack. The front-line troops drove out, and the migrant workers behind pushed carts and carts, drove donkeys, pulled food, and burned them. Once attacked, it is completely for nothing, and the problem of food and grass has become a drag.

However, this fatal problem, the military generals of the Song Dynasty did not solve it well, whether it was Taizong's Northern Expedition, or Yuanfeng's Xia, Xining's Frontier, and Lianjin's Invasion of Liao, logistics became a drag on them, and they repeatedly made mistakes, but no one summarized and improved......

Liao Taizong Yelu Deguang led tens of thousands of troops, and the general Du Chongwei led 200,000 troops to meet the battle, but the Liao army cut off its grain and grass, cut off its retreat, and won a complete victory. When Yuanfeng invaded the summer, the Western Xia army played the role of cavalry, constantly attacked the transportation line of the Song army, and the baggage traveled through the west of Jingyuguan in Lanzhou, and was suddenly attacked by the enemy, and the grain army was defeated, and Ding Fu trampled on each other, killing thousands of people, and the grain, grass and ploughing cattle were captured by the enemy instead.

After the Northern Expedition of the Dynasty, the military reserves accumulated since Xining and Yuanfeng have been exhausted, and the Zuozang Treasury and the government treasury of various places are empty, resulting in difficulties in the supply of military food, and the Changsheng army of Guo Yaoshi of Yanshan Prefecture is more than 100,000 people, and the team is expanding day by day, and more than 100,000 Hu of grain is needed every month, all of which are transported by Hedong and Hebei, and the road is difficult to travel due to the civil change, and it is often interrupted. Officers and soldiers looted rich households, blocked roads and robbed, and squeezed out other troops' grain, grass, and silver, and it can be said that the loss of Yanjing was also related to grain and grass.

Therefore, no matter the Liao, Xia, and Jin who fought with the Song army, they all believed that the logistics and baggage transportation lines were his weakness.

A transport team composed of 100 four-wheeled carts and 3 or 400 pack horses set foot on the official road to Taiyuan after a little rest in Lou Fu, they belonged to the transport team of the Loyal and Brave Army's baggage brigade, and undertook the task of transporting this section from Lanzhou to Taiyuan. After entering the road, several caravans also approached and followed them.

After the siege of Taiyuan was lifted, there was a shortage of everything in the city, especially grain, and it was impossible to collect it on the spot. With the entry of the army in the river, there are more than 100,000 people waiting to eat, and the required food needs to be transported from the river to Taiyuan, and the heavy transportation task falls on the volunteers and the baggage brigade.

Now the enemy situation on the ground in Hedong is very complicated, not only the Jin army, bandits, but also the defected Yisheng army and the forbidden army that escaped from Taiyuan, they are all the targets of the Hezhong army. These people, due to the difference in strength or weapons, did not dare to clash head-on with the river army. As a result, there are fewer combatants, and slow-moving convoys become the targets of their attacks!

The supply line of the Hezhong Army was in the area of activity of the Jurchens and the defeated bandits, and the convoys on the transportation line were extremely vulnerable to attack once the battle line was extended. Therefore, the Kamanaka Army took a number of measures, such as minimizing the number of supply bases and shortening their spacing, in order to concentrate forces. In recent days, smaller convoys have often become targets of attacks by the Jin army and large bandits, and have lost a lot of materials and personnel. In view of this, the River Army moved as many transport units as possible together and increased its vigilance.

This time, the transport team led by Lou Qian dispatched a total of 200 carts and 400 pack horses, in addition to weapons and ammunition, 2,000 stone of grain and 100,000 yuan of military salaries, and mobilized 500 troops of the baggage brigade and three volunteer archers under command to be responsible for transportation and vigilance. Don't look at them as just loyal and brave troops, but they are not soft persimmons either!

The soldiers of the baggage brigade can not only complete their own work, but also have received strict military training, learned the basic tactics of the infantry army, and are well-trained in flank attacks, roundabout outflanking, night battles, search alerts, marching organization and other aspects, and their weak combat effectiveness is relative to the combat units of the loyal and brave army...
